It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.

Problems/Comments

Fuel releases from an underground storage tank system probably occurred at he site sometime in the mid-1970s. Contamination associated with the fuel releases was reported in the on-site drinking water well in the mid-1980s. Site investigations confirmed that elevated hydrocarbon constituents were present in the soil and groundwater. Source of contamination was determined to be gasoline.

Advance approval required to transport soil or groundwater off-site. Standard condition.
Movement or use of contaminated material (including on site) in a manner that results in a violation of the water quality standards is prohibited (18 AAC 70) Standard condition.
Groundwater Use Restrictions No groundwater wells may be installed on this property without the review and approval of ADEC.
Maintenance / Inspection Of Engineering Controls The owner/operator of this property shall make a good faith effort to preserve the groundwater monitoring wells (MW-2, MW-4, MW-7, MW-9, MW-10, SPG-2, SPG-4, and 22.5-90-3) for future groundwater quality monitoring. In the event any monitoring wells are damaged, the property owner/operator shall, upon knowledge, notify ADEC promptly so that a timely determination can be made on the repair or replacement of any damaged wells.
